Thank you for the query.
Most likely what you have described are hemorrhoids. And if the thrombus
is inside it can look pretty scary, gives a lot of pain and can get infected resulting with an abscess
. External hemorrhoids (stage III or IV) for sure wont go away by itself. Moreover it can start bleeding causing anemia
. I`m afraid there is no other way for you than surgery. Laser removal can be impossible when thrombus is present.
Surgical removal do not aches at all as it is always done with anesthesia
. After the surgery you will also get pain killers so it should not be painful. And it will permanently set you free from hemorrhoids.
The other problem is that your inability for bowel movement can be caused by something else than hemorrhoids. Therefore you should also have colonoscopy
Diet change and avoiding constipations is also strongly advisable. You should increase fiber rich products, drink more mineral water and increase physical activity.
Hope this will help.
